Teachers and the principal at Loveland High School were among those shaving their heads. They did it in support of Becca Knisken, 6, whose mom is a teacher at the school. Becca is battling leukemia for a second time.

“Events like this really help not only raise money for research and help find a cure, but also (to) raise awareness and help these kids that go through hell really," Becca’s dad, Ethan, said.

6-year-old Jackson Lowe was the youngest participant. He raised over $500 for the organization which contributes more in childhood cancer research grants than any organization except the U.S. government.

Organizers said they surpassed their $15,000 goal and raised more than $18,000.
